西藏的城市发展一直处于缓慢的进程中,城市体系发育迟缓,城市数量少、规模小、形态不完善、分布极不平衡。然而,自元代西藏被正式纳入中央管辖,特别是清代以来,城市却发挥了重要的“固边强区”作用。本文围绕清代以来西藏城市在“固边”、“强区”上的作用,论述了西藏城市的重要历史地位。 The urban development in Tibet has been in a slow process. The urban system is sluggish, the number of cities is small, the scale is small, the shape is imperfect and the distribution is extremely uneven. However, since the Yuan Dynasty, Tibet was formally incorporated into the Central Government, especially since the Qing Dynasty, the city has played an important role in “strengthening the border areas.” This article focuses on the role of Tibetan cities in Tibet since the Qing Dynasty on the “solid border” and “strong zone”, and discusses the important historical status of Tibet's cities.
